PORT 0
Port 0 is controlled directly through the bit-addressable Port 0
SFR (P0, Address 0x80). The weak internal pull-ups for Port 0
are configured through the Port 0 weak pull-up Enable SFR
(PINMAP0, Address 0xB2); they are enabled by default. The
weak internal pull-up is disabled by writing a 1 to PINMAP0.x.
Port 0 pins also have various secondary functions, as described
in Table 163.
The alternate functions of Port 0 pins can be activated only if
the corresponding bit latch in the Port 0 SFR contains a 1.
Otherwise, the port pin remains at 0.
PORT 1
Port 1 is an 8-bit bidirectional port controlled directly through
the bit-addressable Port 1 SFR (P1, Address 0x90). The weak
internal pull-ups for Port 1 are configured through the Port 1
weak pull-up enable SFR (PINMAP1, Address 0xB3); they are
enabled by default. The weak internal pull-up is disabled by
writing a 1 to PINMAP1.x.

Port 1 pins also have various secondary functions as described
in Table 164. The alternate functions of Port 1 pins can be
activated only if the corresponding bit latch in the Port 1 SFR
contains a 1. Otherwise, the port pin remains at 0.
PORT 2
Port 2 is a 4-bit bidirectional port controlled directly through
the bit-addressable Port 2 SFR (P2, Address 0xA0). Note that
P2.3 can be used as an output only. Consequently, any read
operation, such as a CPL P2.3, cannot be executed on this I/O.
The weak internal pull-ups for Port 2 are configured through
the Port 2 weak pull-up enable SFR (PINMAP2, Address 0xB4);
they are enabled by default. The weak internal pull-up is
disabled by writing a 1 to PINMAP2.x.
Port 2 pins also have various secondary functions as described
in Table 165. The alternate functions of Port 2 pins can be
activated only if the corresponding bit latch in the Port 2 SFR
contains a 1. Otherwise, the port pin remains at 0.
